W R KENNEDY GAP FOR FOUNTAIN PENS. APPLICATION FILED ml a, 1900.

v To all whom itmay concern:

WILLIAM lhKENNEDY, OF WASHINGTON, DISTRICT OF COLUMBIA.

Be it known that I, ,WILLIAM R. KENNEDY,

x of Washington, District of Columbia, have invented a new and usefulImprovement in Caps for Fountain-Pens, of which the followin is aspecification.

his invention relates to a closure or cap intended more particularly forfountainpens, the object of the invention being to rovide; ca "whichwill be confined on the arrel or bod yof the pen, but which may be movedforward to cover the penoint when the pen is not in use and drawn ack toexpose the pen-point when the pen is to be used, thus avoiding thenecessity of removing the cap bodily from over the penoint and applyingit to the op osite end 0 the pen, as is necessary with ountain-pen capsnow in general use.

With this end 'n view my invention consists primarily of a closure orcap adapted to close over and cover the penoint and movable rearwardlyon the en bo y or barrel to uncover and expose t e pen-point.

The invention conslsts-also in forming the a cap with a relativelymovable portion adaptof the penoint, so as to expose the end of' ed toopen automatically when the cap is moved rearward.

The invention consists also in constructing the movable portion of theca so that it will open laterally, whereby it wil clear the point 5;)tabs pen when the cap is drawn back on the The invention consists alsoin the details of construction and combination of parts hereinafterdescribed and claimed.

In the preferred embodiment of my invention the cap or closure comprisestwo conical half-shells adapted when in'contact to close over and coverthe point of thepen and separable to uncover the pen-point, the saidshells being ivoted to a carrying-sleeve movable alon 51B barrel of thepen, the movement of the s eeve rearward serving to automaticallyseparate the half-shells to uncover the penpoint andacting to carry themrearward free the pen to t e grasp of the fingers for writing; but itwill be understood that the invention may be embodied in other forms, aswill be more fully described later on and illustrated in the drawings,the essential feature being that the cap or closure will be confined onthe Specification of Letters Patent.

pen-body and will be movable rearwardly to uncover and expose theen-point.

In the accompanying awings, Figure 1 is a side elevation of afountain-pen equipped with my improved cap, the latter being shown inclosed position. Fig. 2 is a similar view with the cap in 0 en positionand 1etraoted on the pen-b0 y elevation of apen, showlng the cap inlongitudinal section and in closed position.v Flg. 4 is a transversesection; on the line a a of Fig. 1. Fig. 5 is a longitudinal sectionthrough-a cap of modified construction and in closed position. Fig. 6 isa similar view of the same opened. Fig. 7 is an end -view of Fig. 6looking in the direction of the arrow in said figure.

Referring to the drawings, referring particularly to Figs. 1 to 4,inclusive, A represents a fountain-pen embodying the barrel portion (1,,carrying, as usual, the pen-point a. B represents my lmproved cap orclo- Fig. 3 is a side sure comprislng two opposing conlcal halfshells bb, pivoted, as at C, to opposite sides of a carrying-sleeve D in suchmanner that they may be spread apart when the cap is to be opened orclosed together over the enpoint, as shown in Figs. 1 and 3, the twoalf- I shells being normally and when in closed position held yieldinglyclosed by means of two curved springs b and b the s ring 12 being fixedat one end to the side of the shell I) and passing horizontally aroundand bearing with a sprin ressure against the opposite side of the shellwhile the spring 1) 1s fixed to the side of the shell I) and passesaround and bears with a s rin -pressure against the opposite side ofiilie s ell b.

When in closed position, the sleeve D and halfshells of the cap are inthe position shown in Fig. 1, at the forward end of thepenbarrel,'.'with the half-shells held yieldingly together by thesprings and conj ointly forming a ca surrounding and covering't epenpoint. 11 opening t e cap when the pen is to be used the sleeve isdrawn rearward along the pen-barrel, which action will cause the innersurfaces of the half-shells to contact with the forward end of thebarrel, and there rearward movement 0 the sleev serving to draw the twoparts of the cap oaok to the r I to the fingers of the user.

point and barrel,

' position illustrated in Fig. 2, thereby ex osmg the pen-point and theadiacent end 0 the barrel, sothat the latter wil be free of anyobstruction and will offer a comfortable grasp In order that the cap mabe 'ded in its movements back and fort an prevented from twisting aroundthe barrel, so thatit may maintain its proper relation to the penform inthe latter' a longitudinal grooveE, adapted to receive a pin e, carriedby the sleeve, the contact of the pin with the ends of the slot actingto limit the forward and rearward movements of the cap 15. and the slotand serving to confine the cap movably on t e pen-barrel. The oppositeends of the slot ma be provided with lateral recesses F, into w 'ch thepin may be I turnedby a lateral twisting motion in order v to lock thecap against. endwise movement when in either of its extreme positions.

Instead of forming the cap with the two spreading or movable sections orshells, as described, but one movable section may be pro- 2 vided, asillustrated in Figs. 5, 6, and 7, where it will be seen that the sleeveD extends forwardly and continuously at one side and is recessed in itsopposite side to receive a movable section or door G, pivoted in' there- 0 cess on a transverse axis 9 and having its outer end adapted tocooperate with and close against the extended end of the sleeve when thelatter is moved forward, and thereby close over and cover the point ofthe pen.

3 5 The section G is acted on by a fiat spring H, fixed to the sleeveand bearing against the movable section and acting to yieldmgly urge ittoward the extended end of the sleeve, with which it cooperates. Inopening the 0 cap when the pen is to be used the sleeve, as

in the first instance described, is drawn rearward along the body of thepen, which action will cause the section G to open laterally, thecontinued movement of the sleeve causing 5 the parts to be drawnrearward free of the pen-point and adjacent parts of the barrel,

so that the latter may be grasped for writing.

In both instances described the cap is of such form that it is confinedmovably on the en-body, so that it may be moved backandorth, itsconstruction being such that when in its forward position it w1ll closeover and cover the pen-point and when its rearward position thepen-point will be uncovered 5 5 and ex osed.

Whi eIhave illustrated and described a construction by which therearward movement of the cap serves to automatically open it laterally,it will be understood that-this is not absolutely essential to theinvention.

Instead of providing for the automatic opening of the movable part ofthe cap it may be so formed as to be opened independently of themovement of the sleeve and before the 6 5 sleeve is moved rearward. Itis preferable,

The invention is susceptible of variousqo' modifications as regards thedetailed construction and arrangement of the parts. I

believe myself, however, to be the first to provide a closure or capwhich is confined'on the pen-body and movable longitudinally thereof andadapted to respectivel cover and uncover the point of the pen; believemyself also to be the first to rovide a cap or closure whichislongitudinal y movable on the pen bod and which opens in a lateraldirection. I be ieve myself to be the first also to provide a cap orclosure which when moved rearwardly along the pen-body will beautomatically opened to expose thenpen-point. It isob vious, therefore,that the invention may be embodied in various specific constructionswithout departin from the limits of my invention, provide the operationis substantially as set forth. I

Having thus described my invention, what I claim is 1. In combinationwith a fountain-pen, a laterally-opening cap or closure movablelongitudinally thereon.

2. In combination with a fountain-pen, a 5 cap for the same formed witha relatively movable section adapted to close over the penpoint, andmovable to uncover the same, said cap being movable bodily rearward toexpose the pen-point.
